Tip: Consider using co-registration to give your newsletter a boost (but be careful)

If you're trying to grow a newsletter, partnerships can work wonders. Try co-registration to gain momentum, but make sure you partner with the right brand.

Co-registration is a partnership where people who are subscribing to another newsletter are asked if they'd like to subscribe to yours as well. It's an easy reciprocal relationship that doesn't cost a dime, and it can give you a nice boost in subscribers — particularly in the early stages. In fact, it was one tactic that helped Morning Brew get to where they are today (~2.5MM subs). With that said, it's very important to partner with the right brand. After all, getting new subscribers who aren't aligned with (or interested in) your content will lead to unsubscribes and low open rates. So if you give it a shot, make like a PB&J, and partner with a newsletter that perfectly complements your own.
